I have a problem in NetBeans with Command-Line Arguments, when run this code it says
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
Note I put an argument in command line for NetBeans
public class NewEmpty1
{
public static void main(String arg[]){
System.out.println(arg[0]);
}
}
What is wrong ?
goto Project-Property-Run here you will see the option main class arguments
now make sure you are accessing the correct main class....after this option you have button to browse the class path. select it and then select the arguments finally you should be able to run the program...cheers!

You have not passed any arguments..
And if you have passed arguments then it may be because you are invoking another class main method in the same package
the best way would be to iterate..
for(string s:arg)
System.out.println(s);
or
for(int i=0;i<arg.length();i++)
System.out.println(arg[i]);
subscript the string beyond its index is undefined.
this is your case. args[] is empty.
check this How to pass cmd line argument
public class NewMain {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
int argslen=args.length;
int argsValue[] = new int[argslen];
for (String i:args) {
int d = 0;
argsValue[d]=Integer.parseInt(i);
System.out.print(argsValue[d]+"\t"+"\n");
}
}
}
